IRISnet: A self-evolving BPoS cross-chain service hub. Like the Greek rainbow goddess Iris, who serves as the faithful messenger between heaven and humanity, IRISnet's goal is to become a trusted “bridge” linking the digital economy and the real economy, providing a new generation of public-chain infrastructure for building complex distributed business applications. IRISnet, developed by Border Intelligence and the Tendermint team, will support seamless integration between the public chain, the alliance chain, and traditional business systems, enabling data and complex computing to interoperate across heterogeneous networks for cross-chain calls to services.
